XD Series Single Stage Rotary Vane Vacuum Pump for Laboratory

How to choose the vacuum pump used in the laboratory is a problem that troubles many users. After purchasing a vacuum pump, many users will encounter insufficient vacuum (not enough suction), too slow pumping speed, noise, or oil mist when the pump is used. These problems are often related to the vacuum pump selection.


Users may not be able to figure out the relationship between the parameters of the single-stage rotary vane vacuum pump and the actual use effect. Generally speaking, users mainly consider the following factors when purchasing a laboratory vacuum pump:  


  1. Whether the working environment needs to ensure that there is no pollution

Due to the design principle of some vacuum pumps, other media need to be used to assist the operation of the pump, such as oil rotary vane vacuum pumps and water circulation vacuum pumps, which need to be poured into the pump oil or connected to the water source.

For the rotary vane vacuum pump, when the pump oil is used, the oil mist will be emitted into the air, polluting the environment. For the water ring vacuum pump, the pump must be used next to the water sink because it needs to be connected to the water source. And some customers who need to aspirate the cell culture supernatant in the clean room of the cell room cannot use this product. At this time, user should choose an oil-free vacuum pump, which can be used when plugged in.  


  1. What kind of equipment is being used together

Different equipment are used for different purposes. Some require a higher vacuum degree, such as vacuum distillation. Some require higher pumping speed, such as a vacuum drying oven, which needs to consider the internal volume of the box. While vacuum filtration is more complicated, and it is necessary to examine the filtrate capacity of the filter, the particle content in the liquid, and then select the appropriate vacuum degree or pumping speed according to different situations.  


  1. The volume size of the matching equipment

There is a correlation between the volume of the equipment and the pumping speed parameters of the vacuum pump. For example, when used with a general 1000ml vacuum filter bottle, we only need to use the smallest vacuum filter pump with a pumping speed of 20L/min.  


  1. What accessories are needed to ensure normal use

The lack of accessories in the use of some vacuum systems can make operation very difficult. For example, the vacuum regulating valve plays a very important role in many applications. It can observe the working state of the system and adjust the pumping speed according to actual needs. When performing vacuum filtration, the anti-suckback accessory set, including buffer bottle and water blocking filter, can effectively avoid the problem of vacuum pump damage due to suction, and is a very useful set of accessories.  


XD series single stage rotary vane vacuum pump in the laboratory mainly includes the following aspects:   

  • Vacuum filtration

XD series rotary vane vacuum pump can be matched with various laboratory vacuum filtration devices, such as solvent filters, sand core filter bottles, funnel filter bottles, bottle top filters, microbial limit detection filter devices, multi-stage filters, etc.

Due to its high vacuum degree and pumping speed, laboratory vacuum pumps are especially suitable for matching large-capacity filter bottles and multi-stage filters with a large number of channels. When the situation is difficult, such as the detection of suspended solids in water, filtration or samples with high solid content, the use of laboratory vacuum pumps can achieve excellent results.


  • Vacuum drying

XD series rotary vane vacuum pump is suitable for use with a small vacuum drying tank or vacuum drying box. Using a laboratory vacuum pump eliminates the need to replace the pump oil, saves unnecessary trouble, and has lower noise.


XD series single-stage rotary vane vacuum pump has the advantages of stable performance, strong durability, strong power, no oil mist in exhaust gas, low noise and low vibration etc.
